2017 State of Storage in Virtualization
For the second year, Tegile has partnered with ActualTech Media to research how storage and virtualization trends track with one another and how respondents view technologies such as VMware’s VVols. With responses from more than 700 IT pros and IT leaders, you will discover the applications and storage characteristics that are important today and how respondents’ thoughts have shifted over the past year.
Learn how storage has become the key enabler to bigger and faster virtualization. Key findings:
•    Virtualized instances of SQL Server continue to increase in popularity.
•    Hybrid flash storage (combination of flash and spinning disk) gains even more traction. Hybrid storage systems are now found in 55% of respondent environments.
•    Storage performance issues persist. The majority of respondents indicate that they experience storage performance challenges.
•    iSCSI now exceeds Fibre Channel in deployment popularity. 50% of respondents indicated that iSCSI is one of their protocols of choice.
•    VMware VVols continues to be panned by customers. 66% respondents feel that they have little to no knowledge of VVols.

Remove complexity in protecting your virtual infrastructure with IBM Spectrum Protect Plus
This white paper focuses on the deployment and basic setup of IBM Spectrum Protect Plus for protecting VMware. Readers will be taken through a step-by-step explanation of what is required to install and configure IBM Spectrum Protect Plus for basic backup and recovery of VMware virtual machines (VMs). Integration with Spectrum Protect for long-term data retention is also discussed.
IBM Spectrum Protect™ Plus is a new data protection and availability solution for virtual environments that can unlock your valuable data for emerging use cases. You can deploy it in minutes and have your environment fully protected within an hour. IBM Spectrum Protect Plus can be implemented as a stand-alone solution or can integrate easily with your IBM Spectrum Protect environment to off-load copies for long-term storage and governance with scale and efficiency.

The Next Generation Clusterless Federation Design in the Cloudistics Cloud Platform
Is there another way to manage your VMs? Yes, the introduction of the Cloudistics Cloud Platform has an innovative approach – non-clustered (or clusterless) federated design.The clusterless federation of the Cloudistics Cloud platform uses categories and tags to characterize computer nodes, migration zones, and storage groups (or blocks). With these benefits: ⦁ Node Limits Are A Thing of the Past. ⦁ Locking limitations are removed. ⦁ Flexibility is Enhanced. ⦁ Ladders of Latency are Removed. ⦁

This paper is written in the context of modern virtualized infrastructures, such as VMware or Nutanix. In such systems, a hypervisor runs on each compute node creating multiple virtual machines (VMs) per compute node. A guest OS runs inside each VM.

Data associated with each VM is stored in one or more virtual disks (vDisks). A virtual disk appears like a local disk, but can be mapped to physical storage in many ways as we will discuss.

Virtualized infrastructures use clustering to provide for non-disruptive VM migration between compute nodes, for load balancing across the nodes, for sharing storage, and for high availability and failover. Clustering is well known and has been used to build
computer systems for a long time. However, in the context of virtualized infrastructures, clustering has a number of significant limitations. Specifically, as we explain below, clusters limit scalability, decrease resource efficiency, hurt performance, reduce flexibility and impair manageability.

In this paper, we will present an innovative alternative architecture that does not have these limitations of clustering. We call our new approach clusterless federation and it is the approach used in the Cloudistics platform.

The rest of this paper is organized as follows. In Section 2, we describe the limitations of clustering and in Section 3, we drive the point home by using the specific example of VMware; other virtualized systems are similar. In Section 4, we present the clusterless federated approach and show how it avoids the limitations of clustering. We summarize in Section 5.
